E. PLATT STRATTON, OF COLLEGE POINT, ASSIGNOR TO THE STRATTON SEPARATOR COMPANY, OF NEW YORK, N. Y.

STEAM-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 323,891, dated August 4, 1885.

Application filed January 29, 1885.

To all whom it may concern.-

Be it known that I, E. PLATT STRATTON, a citizen of the United States, residing at College Point, in the county of Queens and State of New York, have invented a new and useful Improvement in Steam-Separators, of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 is a cross-sectional view on the line a: w of Fig. 2, the latter representing a central vertical section of a device embodying my invention.

This invention consists in certain improvements in form and internal construction upon the separator referred to in Letters Patent of the United States granted November 15, 1881, No. 249,446; and in order that others may understand and apply said improvements, I will first proceed to describe a separator embodying the same, and subsequently to point out the novel features in the claims.

In the drawings, the shell A is made up of separable sections, joined together by athreaded connection or by bolted flanges, as shown. The top or cap section, a, is composed of castiron, and provided with a vertical and a tangential opening, with projecting nozzles and flanges to accommodate pipe-connections. The connected cylindrical section b is made of wrought-iron, and the following or waist section 0 made of cast-iron, in flaring form, to increase the diameter of the device at its base portion, such portion being made up of a cylindrical section, d, of wrought-iron, and a V- shaped bottom section, 6, of cast-iron.

The object of enlarging the lower portion of the device is to increase the capacity of the trap or water-chamber to any desired degree, and also to keep the separated water sufficiently clear of the current of steam to prevent the latter from carrying said water into the steam-circulation, and, further, the area surrounding the suspended curtain is so comparatively small that a rapid circular action of the steam is maintained therein, and the increased diameter at and below the bottom of the suspended curtain causes a reduced velocity at that point where a change in the direction of the current of steam takes place.

B isa suspended curtain in theform of apipe,

(No model.)

connecting with the vertical orifice through the top or cap section, a, and extending downward about midway of the waist-section c or near the top of the enlarged sectional. This suspended curtain is arranged centrally, and forms a surrounding concentric space, h, communicating with the tangential orifice and the enlarged water chamber or trap.

0 represents a deflecting-shield arranged within the waist-section c, with a water-passage between the same and the shell, and a steam-passage adjacent to the suspended curtain B, the shield extending a distance above and beneath the depending end of the suspended curtain, substantially as indicated in Fig. 2. The shield C may be secured in place so as to be readily detached by means of bayonet-joint fixtures, as shown, or in any other suitable way. The bottom section, e,is made in V-shape, as 'shown, and provided with a suitable discharge-cock, t, for drawing off the accumulated water, a glass gage, is, being also supplied to indicate the quantity of water contained in the trap.

The operation of the device as regards its separating function is similar to that referred to in the former Letters Patent mentioned, the saturated steam being introduced through the tangential orifice into the concentric space h, surrounding the suspended curtain B, whereby a circular motion is imparted to the steam and the water particles thrown by centrifugal action upon the outer surface, upon which it gravitates to the trapchamber, passing outside the deflecting-shield C, while the current of steam follows the suspended curtain to the interior of the shield and escapes in a dry state upward through the suspended curtain B. The shield O practically maintains a division of the dry steam and separated water, and extends so far below the end of the suspended curtain as to prevent the current of steam from again picking up the separated water.

If found necessary in practice, the shield 0 may be extended so far downward as to be immersed in the accumulated water in the trap, which will eifectua-lly separate the steam and water currents.

In Fig. 1 a section of the tangential orifice is shown, having an inwardly-projecting plate, 8, that guides the steam in a direction around IOd the suspended curtain to produce the circular motion des :1'il"e;l. This motion may also be produced and maintained by the introduction of a spiral division-plate, if desired.

I-laving thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a steamseparator having a suspended curtain and arranged to secure a centrifugal action of the steam, as described, an enlarged chamber below the bottom of said suspended curtain, substantially as and for the purposes specified.

2. In a steam-separator arranged to secure a centrifugal action to the steam, a shield surrounding the lower portion of the suspended curtain, to prevent any moisture which may adhere to the external sides from being picked up by the steam and carried into the circulation, substantially as described.

8. A steam-separator consisting of a headpiece with tangential opening, a straight body, an internal suspended curtain, a flaring waist, and an enlarged chamber, substantially as de scribed.

4. A steam-separator consisting of a headpiece with tangential opening, a straight body, an internal suspended curtain, an enlarged chamber, and a shield Within the expanded waist, substantially as described.
